Concerning the accompanying Eleusinian form (Fig. 24), Calmet says:--'The mysterious trunk, coffer, or basket, may be justly reckoned among the most remarkable and sacred instruments of worship, which formed part of the processional ceremonies in the heathen world. This was held so sacred that it was not publicly exposed to view, or publicly opened, but was reserved for the inspection of the initiated, the fully initiated only. Completely to explain this symbol would require a dissertation; and, indeed, it has been considered, more or less, by those who have written on the nature of the Ark of the testimony among the Hebrews. Declining the inquiry at present, we merely call the attention of the reader to what this mystical coffer was supposed to contain--a serpent!' The French Benedictine who wrote this passage, though his usual candour shames the casuistry of our own time, found it necessary to conceal the Hebrew Ark: it was precisely so that the occupant of the Ark was originally concealed; and though St. John exorcised it from the Chalice its genius lingers in the Pyx, before whose Host 'lifted up' the eyes of worshippers are lowered. The writer of the Epistle to the Hebrews (chap. ix.), describing the Tabernacle, says: 'After the second veil, the tabernacle which is called the Holiest of all; which had the golden censer, and the ark of the covenant overlaid round about with gold, wherein was the golden pot that had manna, and Aaron's rod that budded, and the tables of the covenant.' But this rod of Aaron, which, by budding, had swallowed up all rival pretensions to the tribal priesthood, was the same rod which had been changed to a serpent, and swallowed up the rod-serpents of the sorcerers in Pharaoh's presence. So soft and subtle is 'the way of a serpent upon a rock!'
